Root Canal Treatment in Markham

Root canal treatment, also known as endodontic therapy, is a dental procedure used to treat infection or damage inside a tooth. Each tooth contains a soft core called the pulp, which contains nerves, blood vessels, and connective tissue. When this pulp becomes infected or inflamed — due to deep decay, a crack, or trauma — a root canal is performed to remove the affected tissue and preserve the tooth.

During the procedure, your dentist removes the infected pulp, cleans and shapes the root canals, and seals the tooth to prevent reinfection. In most cases, a dental crown is placed afterward to protect and restore the treated tooth.

Root canal treatment is one of the most effective ways to save a natural tooth that might otherwise need to be extracted. Preserving your natural teeth is generally the preferred approach, as it supports healthy chewing function, maintains jaw bone density, and avoids the need for tooth replacement options such as implants or bridges.

Several symptoms may indicate that the pulp of a tooth is infected or damaged. These do not always mean a root canal is required, but they do warrant prompt professional evaluation at our Markham clinic.

Common warning signs include persistent or severe toothache, especially when biting or applying pressure; prolonged sensitivity to hot or cold temperatures even after the stimulus is removed; darkening or discolouration of the tooth; swelling or tenderness in the surrounding gum tissue; and a recurring pimple-like bump on the gums near the tooth.

In some cases, an infected pulp may cause no noticeable pain at all. This is why regular dental check-ups are important — issues can be identified on X-rays before they become symptomatic. If you are experiencing any of these signs, contact Smile Dental Arts Centre in Markham for an evaluation.

The root canal process at our Markham clinic typically involves one to two appointments, depending on the complexity of your case. We begin with a thorough examination and digital X-rays to assess the extent of the infection and plan your treatment.

Local anaesthesia is administered to ensure you are comfortable throughout the procedure. Many patients report that a root canal feels similar to having a filling placed. Once the area is numb, a small opening is made in the crown of the tooth to access the pulp chamber. The infected or damaged pulp is carefully removed, and the root canals are cleaned, shaped, and disinfected.

The canals are then filled with a biocompatible material called gutta-percha and sealed. In most cases, a temporary filling is placed, and a follow-up appointment is scheduled to place a permanent crown or restoration. The crown restores the tooth's shape, strength, and function, protecting it for years to come.

Most patients experience mild soreness or sensitivity for a few days after a root canal, which can typically be managed with over-the-counter pain relievers. Your dentist may also prescribe antibiotics if infection was present.

Avoid chewing on the treated tooth until the permanent crown or restoration is in place, as it may be more vulnerable to fracture during this period. Continue brushing and flossing normally, and attend your follow-up appointment as scheduled.

With proper care, a root canal-treated tooth can last many years or even a lifetime. Good oral hygiene, regular dental visits, and prompt attention to any new concerns all contribute to the long-term success of your treatment.

The cost of root canal treatment varies depending on which tooth is being treated (front teeth are generally less complex than molars), whether a crown is required, and the specifics of your case. We will provide you with a clear cost estimate before beginning treatment.

Many dental insurance plans cover a portion of root canal therapy costs. We recommend reviewing your plan details or contacting your insurer directly to understand your coverage. The Canadian Dental Care Plan (CDCP) may cover endodontic treatment for eligible Canadians — ask our team for more information.
